This design is a scratch-card-style sticker for medicine bottles that "gamifies" taking medication in order to encourage patients to remember to take their daily dose. While FebriSol is designed to be used with any daily medication, the project has a special focus on the antiretrovirals (ARVs) used to combat HIV. The patient simply sticks the label on their bottle, box or packet and scratches off the day's metallic coating after taking their medication. "By doing this they reveal a green tick providing positive reinforcement, essential to making behavioural change sustainable," Stoch told Dezeen. "The patient can also see, at a glance, whether or not they have taken their medication on any given day." Stoch took cues from the contraceptive pill's packaging design when creating the label, which features 28 days that run as a loop before ending back at the start.
